Null-controllability for some linear parabolic systems with controls acting on different parts of the domain and its boundary

Guillaume Olive

In this work we study the null-controllability properties of linear parabolic systems with constant coefficients in the case where several controls are acting on different distribu…

Validation of optical pathlength stability in a LISA test-bench demonstrator

Shivani Harer, Maxime Vincent, Hubert Halloin +40

The Laser Interferometer Space Antenna (LISA) observatory is a future L3 mission of the European Space Agency (ESA) to detect gravitational waves, set to launch in 2035. The detect…

Euclid Structural-Thermal-Optical Performance

Euclid Collaboration, A. Anselmi, R. Laureijs +290

The Euclid system performance is defined in terms of image quality metrics tuned to the weak gravitational lensing (WL) cosmological probe. WL induces stringent requirements on the…

Euclid Quick Data Release (Q1): Hunting for luminous z > 6 galaxies in the Euclid Deep Fields -- forecasts and first bright detections

Euclid Collaboration, N. Allen, P. A. Oesch +309

The evolution of the rest-frame ultraviolet luminosity function (UV LF) is a powerful probe of early star formation and stellar mass build-up. At z > 6, its bright end (MUV < -21)…
